According to some search engines, extrusion is the process used to develop or create objects with a fixed cross sectional profile. The material is drawn or pushed through a dye of a desired cross section. The 2 main advantages of the extrusion process is its ability to develop complex cross sections and materials which are brittle since these materials only encounter shear and compressive stresses. In addition it can also create finished parts with a beautiful surface finishing. Examples of the items that can be extruded include, metals, ceramics, foodstuff, polymers, and concrete. There are numerous types of extrusion machinery including plastic extrusion machinery, steel extrusion machinery and aluminum extrusion machinery.
The industrial sector today is ready for greater growth. Each passing year, FDI continues to grow and the market seems bullish. A lot of economists are nowadays advocating for a bigger investments in the industrial sector, especially the industrial machinery sector for laying a foundation for a robust growth. These economists insists that non-machinery products and manufacturing sector are expected to not only perform well, but also holds a potential in creating close to 223400 jobs.
The plastic extrusion machinery, electronic ballasts and hot rolling mills are a few of the key sectors which are expected to be responsible for a tremendous growth according to the industry insiders.
The plastic extrusion machinery are one of the sought after machines and their demand often out paces the supply. The process of plastic extrusion basically involves melting of the raw plastic and later on giving them the desired shapes and sizes according the markets demand. Tubes, adhesive tape, window frames, deck railings, wire insulation, fence and pipes are a few of the materials which can be produced from the plastic extrusion machinery.
Nowadays, many companies have taken up the extrusion of aluminum. Such companies specialize in the creation of aluminum products for their buyers. The aluminum extrusion machinery mainly plays the role of producing homogeneous cross section. The process is done through squeezing an aluminum materials through an outlet under a high pressure. The aluminum extrusion machines are very popular around the world because the metal is readily available on the crust of the earth. Additionally, aluminum is used in a lot of applications and also has several advantages.
Compared to steel and plastic extrusion machinery products, the products of aluminum extrusion have a longer life. The process of extrusion is also considered to be an environment friendly solution.
According to the latest forecast, the employment capacity has registered a huge growth in 2010 and is expected to show further growth in 2011 in all the sectors.
